Algae on rooftops is a fact of life in certain humid climates. It grows organically as a thin film, but can be removed easily with water. Moss is a bit thicker but can be removed with the right substances. Here are proactive ways to prevent the growth of algae, moss and mold and determine whether or not you need shingle roof replacement.

Problems with Algae Buildup

  • discolors shingles
  • leaves dark streaks on shingles, giving a dirty look
  • potentially lowers property value

If you are trying to maintain or increase property value, you need to pay attention to the components of curb appeal. The roof is one of the biggest factors in shaping perceptions of the home’s image. When shingles don’t look clean, buyers are less impressed because it adds to their column of expenses, even if there is nothing structurally wrong with the roofing system. It might instantly paint the picture of a costly shingle roof replacement in their minds.
